Abstract
Buried river channels are increasing becoming the target for groundwater exploration due to the unreliability of surface river channels that have been affected by climate changes. Areas located in urban centers like Nakuru town have high population that dictates the higher demand of water. This research covered the geophysical mapping of buried river channels and other shallow structures recharging major aquifers in the upper Nakuru basin of Kenya rift and in particular the Kabatini area. The project aimed at unveiling scientific knowledge of the subsurface geology using resistivity and magnetic geophysical methods. Solving of water shortages and improvement of livelihood for the people of Nakuru and its neighbor hood through proper and more precise geophysical ground water exploration methods was of great importance. The ultimate goal of the report is to provide guidance to policy makers in decision making especially for ground water extraction in Kabatini aquifer. Geology and hydro-geology of the area have been discussed in the report. The field methods used included vertical electrical sounding, electrical resistivity tomography and magnetic survey. Data processing was done using Earth imager software, RES2DINV, and Euler. The findings of the research ascertain that Kabatini area has underground river channel that flows in the north – south direction. The research also shows that the area has some shallow structures which contain low resistivity materials in different locations. It has also been ascertained that the thickness of Kabatini aquifer is more than 150 m.
